Availability

S-Plus version 6 is currently installed Kellogg's UNIX server, Skew3. The license allows up to three concurrent users. S-Plus is also available in the SSCC cluster.

Description

S-Plus is a programming environment for data analysis. Highlights of S-Plus are its graphic capabilities, its orientation to exploratory data analysis and data mining, and the inclusion of many non parametric statistical methods. The main disadvantage of S-Plus is the steep learning curve to learn the programming language. S-Plus is based on the S language, developed at Bell Laboratories by statistician John M. Chambers.

Running S-Plus

S-Plus is an object oriented programming language. The first time a user launches S-Plus, it will create a directory called "MySwork" in the user's home directory. Within the "MySwork" directory, S-Plus stores its objects in a sub-directory called ".Data".

To ... The command is
Start an interactive S-Plus session splus
End an S-Plus session q()
Run S-Plus in graphic mode under UNIX splus -g &
Run S-Plus in batch mode splus BATCH input outputfile
To open a graph window (X Windows session) motif()
To send a graph to a postscript file postscript("outfile.ps")
To close the postscript device graphics.off()

Alternatively, quit S-Plus
